Java：嵌套树结构
我正在寻找一种在 GUI 中创建嵌套树结构的方法。我有几个“盒子”，里面装有物品。我希望这些框在单击时折叠但展开，就像在侧边栏上导航文件夹的方式一样。我考虑的第一种方法是将“盒子”视为 JList，每个盒子中的项目存储在嵌套的 JList 中。这似乎是一种非常复杂且糟糕的方法。它还可以防止盒子在没有对动作监听器进行大量修改的情况下折叠。我希望有人可能知道一个可能用于显示此处可能使用的文件导航的 API。
I am looking for a way to create a nested tree structure in my GUI. I have a few "boxes" that have items in them. I would like the boxes to be collapsed but expanded when clicked on, like the way folders are navigated on the sidebar. The first way I considered was treating the "boxes" as JList, with the items in each box stored in a nested JList. This seems like a very complicated and poor way of doing it. It also prevents the boxes from being collapsible without extensive modifications to the actionlistener. I was hoping someone might know of an API perhaps for displaying file navigation that might be used here.
